Abstract

Abstract Background Schistosome and soil-transmitted helminth (STH) infections are recognized as major global public health problems, causing severe and subtle morbidity, including significant educational and nutritional effects in children. Although effective and safe drugs are available, ensuring access to these drugs by all those at risk of schistosomiasis and STHs is still a challenge. Community-directed intervention (CDI) has been used successfully for mass distribution of drugs for other diseases such as onchocerciasis and lymphatic filariasis. A national control programme is yet to be instituted in Kenya and evidence for cost-effective strategies for reaching most affected communities is needed. This study evaluated the effectiveness and feasibility of the CDI strategy in the control of schistosomiasis and STHs, in East Uyoma location, Rarieda district, a community of western Kenya that is highly endemic for both infections. Results Pre-treatment prevalence of S. mansoni averaged 17.4% (range 5-43%) in the entire location. Treatment coverage in different villages ranged from 54.19 to 96.6% by community drug distributor (CDD) records. Assessment from a household survey showed coverage of 52.3 -91.9% while the proportion of homesteads (home compounds) covered ranged from 54.9-98.5%. Six months after one round of drug distribution, the prevalence levels of S. mansoni, hookworm and Trichuris trichura infections were reduced by 33.2%, 69.4% and 42.6% respectively. Conclusions This study shows that CDI is an accepted and effective strategy in the mass treatment of schistosomiasis and STH infections in resource constrained communities in Kenya and may be useful in similar communities elsewhere. A controlled trial comparing CDI and school based mass drug administration to demonstarte their relative advantages is ongoing.

Abstract

Abstract Background Understanding the relationship between Plasmodium falciparum malaria transmission and health outcomes requires accurate estimates of exposure to infectious mosquitoes. However, measures of exposure such as mosquito density and entomological inoculation rate (EIR) are generally aggregated over large areas and time periods, biasing the outcome-exposure relationship. There are few studies examining the extent and drivers of local variation in malaria exposure in endemic areas. Methods We describe the spatio-temporal dynamics of malaria transmission intensity measured by mosquito density and EIR in the KEMRI/CDC health and demographic surveillance system using entomological data collected during 2002–2004. Geostatistical zero inflated binomial and negative binomial models were applied to obtain location specific (house) estimates of sporozoite rates and mosquito densities respectively. Model-based predictions were multiplied to estimate the spatial pattern of annual entomological inoculation rate, a measure of the number of infective bites a person receive per unit of time. The models included environmental and climatic predictors extracted from satellite data, harmonic seasonal trends and parameters describing space-time correlation. Results Anopheles gambiae s.l was the main vector species accounting for 86 % (n = 2309) of the total mosquitoes collected with the remainder being Anopheles funestus. Sixty eight percent (757/1110) of the surveyed houses had no mosquitoes. Distance to water bodies, vegetation and day temperature were strongly associated with mosquito density. Overall annual point estimates of EIR were 6.7, 9.3 and 9.6 infectious bites per annum for 2002, 2003 and 2004 respectively. Monthly mosquito density and EIR varied over the study period peaking in May during the wet season each year. The predicted and observed densities of mosquitoes and EIR showed a strong seasonal and spatial pattern over the study area. Conclusions Spatio-temporal maps of malaria transmission intensity obtained in this study are not only useful in understanding variability in malaria epidemiology over small areas but also provide a high resolution exposure surface that can be used to analyse the impact of transmission on malaria related and all-cause morbidity and mortality.

Abstract

Many females lack access to water, privacy and basic sanitation&mdash, felt acutely when menstruating. Water, sanitation and hygiene (WASH) conditions in schools, such as access to latrines, water, and soap, are essential for the comfort, equity, and dignity of menstruating girls. Our study was nested within a cluster randomized controlled pilot feasibility study where nurses provided menstrual items to schoolgirls. We observed the WASH conditions of 30 schools from June 2012&ndash, October 2013 to see if there were any changes in conditions, to compare differences between study arms and to examine agreement between observed and teacher-reported conditions. Data came from study staff observed, and school teacher reported, WASH conditions. We developed scores for the condition of school facilities to report any changes in conditions and compare outcomes across study arms. Results demonstrated that soap availability for students increased significantly between baseline and follow-up while there was a significant decrease in the number of &ldquo, acceptable&rdquo, latrines. During the study follow-up period, individual WASH indicators supporting menstruating girls, such as locks on latrine doors or water availability in latrines did not significantly improve. Advances in WASH conditions for all students, and menstrual hygiene facilities for schoolgirls, needs further support, a defined budget, and regular monitoring of WASH facilities to maintain standards.

Abstract

Background: Diarrhea is a leading cause of childhood morbidity and mortality in sub-Saharan Africa. Data on risk factors for mortality are limited. We conducted hospital-based surveillance to characterize the etiology of diarrhea and identify risk factors for death among children hospitalized with diarrhea in rural western Kenya. Methods and Findings: We enrolled all children Conclusion: Nontyphoidal Salmonella and Shigella are associated with mortality among rural Kenyan children with diarrhea who access a hospital. Improved prevention and treatment of diarrheal disease is necessary. Enhanced surveillance and simplified laboratory diagnostics in Africa may assist clinicians in appropriately treating potentially fatal diarrheal illness. Please see later in the article for the Editors' Summary., Introduction Diarrhea is a major cause of morbidity and mortality among children New tools to combat severe illness and death from rotavirus gastroenteritis have been developed [5-7]; recently, the World [...]

Abstract

Measles is a leading cause of child mortality, and reduction of child mortality is a key Millennium Development Goal. In 2014, the World Health Organization and the U.S. Centers for Disease Control and Prevention developed a measles programmatic risk assessment tool to support country measles elimination efforts. The tool was pilot tested in the State of Uttarakhand in August 2014 to assess its utility in India. The tool assessed measles risk for the 13 districts of Uttarakhand as a function of indicator scores in four categories: population immunity, surveillance quality, program delivery performance, and threat. The highest potential overall score was 100. Scores from each category were totaled to assign an overall risk score for each district. From this risk score, districts were categorized as low, medium, high, or very high risk. Of the 13 districts in Uttarakhand in 2014, the tool classified one district (Haridwar) as very high risk and three districts (Almora, Champawat, and Pauri Garhwal) as high risk. The measles risk in these four districts was largely due to low population immunity from high MCV1-MCV2 drop-out rates, low MCV1 and MCV2 coverage, and the lack of a supplementary immunization activity (SIA) within the past three years. This tool can be used to support measles elimination in India by identifying districts that might be at risk for measles outbreaks, and to guide risk mitigation efforts, including strengthening routine immunization services and implementing SIAs.
